$U$ -spin sum rules for two-body decays of bottom baryons

Si-Jia Wen, Wei-Chen Fu, Di Wang

$U$ -spin symmetry, which reflects the symmetry between the down-type $d$ and $s$ quarks, is a powerful tool for analyzing heavy hadron weak decays. Motivated by recent experimental…

Topological amplitudes of bottom baryon decays in the $S U (3)_{F}$ limit

Di Wang, Wei-Chen Fu

Motivated by the first observation of CP violation in baryon decays, we study the topological amplitudes of bottom baryon decays in the $S U (3)_{F}$ limit. The topological diagrams of…

Isospin sum rules for bottom-baryon weak decays

Wei-Chen Fu, Si-Jia Wen, Di Wang

Isospin symmetry, as the most precise flavor symmetry, can be used to extract information about hadronic dynamics. The effective Hamiltonian operators of bottom quark weak decays a…
